HARROW.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed January 18, 1908. Serial No. 411,523.

To all whom it may concern:

Be it known that I, FRANK GERMON, a citizen of the United States,residing at Leadville, in the county of Lake and State of Colorado, haveinvented a new and useful Harrow, of which the following is aspecification.

This invention has relation to harrows and it consists in the novelconstruction and arrangement of its parts as hereinafter shown anddescribed.

The object of the invention is to provide a harrow with rollers at itsforward and rear ends which are so mounted as to automatically rise orfall in order to relatively elevate or lower the harrow. That is to say,when the implement is drawn in one direction the rollers areautomatically elevated and the harrow member is correspondingly loweredso that its teeth may engage the ground. Vhen the harrow is drawn in theopposite direction the rollers are automatically lowered and the harrowmember is correspondingly elevated so that its teeth are ralsed abovethe surface of the ground and the implement may be readily transportedfrom place to place. The automatic movement of the rollers in verticaldirections is accomplished through the instrumentality of peculiarguides attached to the harrow and which are engaged by the shaft of therollers.

Figure 1 is a top plan view of the harrow. Fig. 2 is a side elevation ofthe same showing the rollers in their lowermost positions, and Fig. 3 isa side elevation of one end of the harrow showing the rollers in anelevated position. i

The harrow 1 may be of any desired style or configuration and isprovided with the usual teeth 2.. The brackets 3 are attached to thefront andrear ends of the harrow 1 and the said brackets are providedwith the arcuate uides 4 which terminate at their lower en s in thebearings 5 and at their upper ends in the bearings 6. The chords of thearcs which the said guides 4 describe are vertically disposed and theguides 4 of the forward brackets 3 are parallel with the guides 4 of thebrackets at the rear end of the harrow. A roller 7 is located at theforward and rear ends respectively of the harrow 1 and the shafts 8 ofthe said rollers enter the guides 4 of the brackets 3 and are adapted torotate in the bearings 5 or 6 according to the direction in which theharrow 1 is moved. The harrow 1 is provided at its op )osite ends withthe clevis supports 9 to eit er one of which a team of draft animals maybe attached for the purpose of drawing the implement.

The harrow is operated as follows: When it is desired that the teeth 2shall engage the ground the draft animals are attached to the clevissupport 9 which is located in front of the concaved edges of the guides4. Consequently, as the harrow 1 is moved over the surface of the groundthe shafts 8 will work up along the guides 4 and eventually will enterthe upper bearings 6. Thus, the rollers will operate upon the surface ofthe ground and regulate the de th at which the teeth 2 will work in thesoi When it is desired to remove the harrow from the field withoutpermitting the teeth 2 to engage the ground the draft animals areconnected to the clevis support 9 at the opposite end of the harrow whenthe shafts 8 will work down through the guides 4 and enter the lowerbearings 5. Thus, the harrow 1 is bodily elevated and will remain insuch osition so long as the harrow is being moved by a pull exerted fromthe convex edges of the guide 4 and may be readily trans orted fromplace to place without having t e teeth 2 in contact with the ground.

Having thus described my invention, what I claim as new and desire tosecure by Letters-Patent is:

A harrow comprising a frame, brackets secured to the ends thereof, saidbrackets having arcuate guides, the guides at the two ends of the framebeing parallel and the chords thereof being substantially vertical orperpendicular to the frame, there being recesses extending in the samedirection from the upper and lower ends of the guides and constitutingupper and lower bearings, and rollers at the ends of the frame andjournaled at their ends in the guides, said rollers and bracketsconstituting means for automatically raising the frame when draft isapplied to one end thereof and seating the ends of the my own, I havehereto aflixed my signature rollers in the lower bearing recesses, andhfor in the presence of two Witnesses. automatically lowering the frameW en draft is applied to the 0 posite ends thereof E FRANK GERMON' 5 andseating the ends of t e rollers in the up- WVitnesses:
